THREAD-CUTTING DEVICE FOR SKEINING MACHiNES.

Application filed March 8, 1928. Serial No. 259,965.

The invention relates to an improvement in thread cutting devices for skeinwinding and binding machines of the type shown in the patent to Man O. Clauss N0. 1301,4319, dated December 27', 1921.

Machines of the type shown in this patent comprise a series of skein holdersymeans for winding thread ,or yarn upon the skein holders successively to -form the slreins, means for moving the skein holders'to present them successively to the skein forming means,

means for placing a binder on each skeinv the machine shown in said patent as is 118C.

essary to illustrate the application of the improved thread cutting device of the present invention thereto; Fig. 2 is a front elevation or the improved-thread cuttingdevice with the associated parts oi the skein winding and binding machine; Fig. 3 isasectional plan taken on the line 33 of Fig. 2, and showing the thread cutting blades in open I position; Fig. 1 is a sectional. plan taken on the line 4 1 of Fig. 2; and showing the thread cutting blades in closed position; and Fig. 5 is an enlarged side elevation :01 the thread cutting blades and oi: their associated parts, and showing their relation to two ad-,

j acent and successivev skeins.

The skeins are wound on a serles of-skein holders 10, 11, 12 mounted on arotatable shaft 13 journaled in the fijame let of the machine. As each skein is wound the shaft 13 is turned in a clockwise direction to preholder 11. will be movedto the position of shein holder 10 and skein holder 12 will move. I into the position of skein holder 11 to 138C61V6- its undersidea roll 28 which travels in a cam the threads forming the new skein. When the uppermost skein holder on which is supported the skein being wound moves to its next successive posit-ion, that occupied by sltein holder 10, thethread from the completed skein isextended, to and constitutes the first winding oi the new skein. This, thread is indicated iii Fig. 1 at 17. Before the slreins are removed from the skein holders it is necessary to part this thread. The thread, parting means shown in the said patent parts thisthread at substantially the middle -point;18,- and this thread parting means is indicated generally at 19. WVhile.

the mechanism 19 and itsactuating means are operating to sever the thread 17, other means of the machine of said patenhindicate'd genorally at 20 and 21, operate to place a binder- 22 5) upon thestrands ofthread'23 extending between the side arms 24; of the slcein holder 10. H i

The thread parting and binding means of saidpatent are carried by an arm 25 pivoted at the point 26. The arm 25 carries on path 29 formed in the periphery of the drum 30 mounted on the shaft 31. The part 20 of the skein binding means islprovidedwith a rack 32v engagedvby a toothed segment 33 .inounted on a vertically arranged shaft 34 journaled in the boss-35 supported on the i underside of the :arm 25. Mounted on the an arm 38 pivoted at thepoint '39 on the arm On its other endthe arm 38 carries a roll 10 adapted'tobe engaged bythe cam surface 11 to turn the arm 38 in a counterclockwise direction to rotate the shaft 34: in a clockwise direction and cause the member 20 to move axially during the skein' binding operation. A spring 42returns the arm 38 to normalcposition. The swinging of the arm 25 under the action of the campath 29 carries the arm 38 and the parts associated with it into and out ofoperative or skein binding position, all as fully described in said patent; i i

'Aifterthe thread parting means 19. have severed the thread 17 extending from skein 15 tonsltein lti and the slrein binding means 20 and 21 have operated to place abinder 22 on the threads extending between the armsv 24 oftheskein holder 10, the shaft- 13 is actu ated to advance the skein holders through an.

other step of their travel. Skeins 15 and 16 now occupy the relative positions indicated at 43 and 44, respectively, in Fig. 5. The upper half of the thread 17, which is now severed, is indicated at 45 and the lower half is indicated at 46. It will be understood that the distance separating the skein holders 10 and 11 in the positions which they occupy in Fig. 1 is about double the distance separating them in the positions they occupy in Fig. 5. Hence the thread ends 45 and 46 each are about equal the: distance separating the skein holders 10 and 11 in Fig. 5. The improved thread cutting-device of the present invention operates to sever the thread end 46 relatively close to the skein holder 10.

The improved thread cutting device comprises a fixed cutting blade 48 and a movable cutting blade 49. The blade 48 is secured to the lower, horizontal part 50 of a bracket 51, the vertically arranged part 52 of which is secured by the screws 53 to the depending part 54 of the forward end of the arm 25. The part 52 of the bracket 51 is provided with a longitudinal slot 55 which permits bracket 51 and the blades carried by it to be adjusted vertically. The movable blade 49 is pivot-- ally mounted at the point 57 on the underside ofthe fixed blade 48. A spring 58 holds the blades in proper cutting relation. On its rear end the blade 49 is provided with an arm 59 oifset at right angles with the blade. On its free end the arm 59 carries an upstanding roll 60 loosely received within a slot 61 formed longitudinally in the arm 62 secured by the screw63 to the lower end of the shaft 34. Vhile the arm 25 is in its inoperative position, as shown in Fig. 1, the parts associated with the movable cutter 59 occupy the positions shown in Figs. 1 and 3, with the blade 49 held separated from the blade 48. hen, however, the arm 25 has been swung in a counter-clockwise direction on its pivot point 26 for the operation of parting the thread 17 and applying a binder on the skein held on the skein holder 10, the open blades 48 and 49 are carried to a position to engage and cut the upstanding end 46 of the skein 43, as shown in Fig. 5. The turning of the shaft 34 during the binding operation causes the arm 62 to be turned in a clockwise direction and thereby swing the arm 59 and the blade 49 on the pivot point 57, closing the blade 49 upon the blade 48 to sever the thread end 46 relatively close to the skein 43.

To assure a proper cutting action by the blades 48 and 49 upon the thread end 46 I provide means for holding the upper part of the thread end 46 during the cutting action. The thread holding means consist of a support in the form of a bracket 65 secured by one of the screws 53 to the front'face' of the vertical part of the bracket 51. A spring member 66 cooperates with the bracket to hold the thread end 4 The spring member 66 is provided with a spiral seection 67 which loosely embraces the lower end of the shaft 34, the free end of the spiral entering a collar 68 secured to the shaft 34. As the arm 25 swings in the counter-clockwise direction to bring the thread parting mechanism 19 and the binding parts 20 and 21 into operative posit-ion, and the open cutter blades 48 and 49 are therebybrought into cutting relation with the upstanding thread end 46, the bracket 65 is moved against the upper part of the thread end 46. Then as the shaft turned in the clockwise direction for the binding operation and the movable cutter blade 49 is closed upon the fined cutter blade 48, the spring member 66 is moved toward the bracket 65 and presses the thread end 46 against the bracket 65, holding it firmly during the thread cutting open tion by the blades 48 and 49. When the shaft 34 is rotated in the reverse direction to move the binding member 20 into inoperative position, the spring member 66 is swung away from the-bracket 65 and thereupon the cut thread end 46 falls to the floor or into a re eptacle.

To prevent the thread end 45 extending downwardly from the skein 44 from being acted upon by the cutters 48 and 49, I provide a deflector 70 for pushing aside the thread end 45. The deflector 70 may be composed of bristles orequivalent material held at their rear ends in-a sccket71 secured to one edge of the part 52 of the bracket 51. The deflector 7O occupies a'position over the cutter blades 48 and 49 and extends in their general direction so that as the arm 25 is swung in the counter-clockwise direction to bring the parts carried by it into operative position, the dcflector 7O encounters thethread end 45 and pushes it out of the way, as clearly shown in Fig. 5.
